Enum Error 

pub enum Error {
    ConfigureDisplaySpi(ConfigError),
    InitDisplay,
    ConfigureTouchSpi(ConfigError),
    FlushFrameBuffer,
    SetOrientation,
}

Error from a CYD ESP display or touch operation.

Most applications propagate this error with ?. Code that reports errors differently by operation can match the preserved source-bearing variants:

use device_envoy_esp::cyd::Error;

fn report(error: Error) {
    match error {
        Error::ConfigureDisplaySpi(source) | Error::ConfigureTouchSpi(source) => {
            // Report the SPI configuration details from `source`.
            drop(source);
        }
        Error::InitDisplay => { /* Display initialization failed. */ }
        Error::FlushFrameBuffer => { /* Sending pixels failed. */ }
        Error::SetOrientation => { /* Changing orientation failed. */ }
    }
}

Variants

ConfigureTouchSpi(ConfigError)

Configuring the touch SPI peripheral failed. See the Error example.

FlushFrameBuffer

A frame could not be flushed to the display. See the Error example.

SetOrientation

Changing the display orientation failed. See the Error example.
